DESCRIPTION OF THE PREFERRED EMBODIMENTS

Throughout the following description, specific details are set forth inorder to provide a more thorough understanding of the invention.However, the invention may be practiced without these particulars. Inother instances, well known elements have not been shown or described indetail to avoid unnecessarily obscuring the invention. Accordingly, thespecification and drawings are to be regarded in an illustrative, ratherthan a restrictive sense.

Referring to the drawings and first to FIG. 1 , there is shown a cornerbead roller apparatus 30. The corner bead roller apparatus includes anelongate mount, in this example a bracket 32. The bracket has a proximalend 34, a distal end 36 and a longitudinal axis 38 extending between theends thereof. Bracket 32 is L-shaped in longitudinal section in thisexample. As seen in FIG. 2 , the bracket includes a first planar portion40 and a second planar portion 42 angled by angle α relative to thefirst planar portion thereof. As seen in FIG. 1 , the planer portionsare generally rectangular prisms in shape in this example; however, thisis not strictly required. Referring back to FIG. 2 , angle α isappropriately equal to 90 degrees in this example, with planar portions40 and 42 being perpendicular to each other in this example.

As seen in FIG. 1 , corner bead roller apparatus 30 includes an elongatemember, in this example an elongate handle or pole 44. The pole istelescoping in this example to selectively adjust the length thereof;however, this is not strictly required. Pole 44 pivotally couples tobracket 32, in this example via a clevis joint 46; however, the latteris not strictly required. The clevis joint includes a clevis 48integrally connected to, formed with and extending outwards from planarportions 40 and 52 of bracket 32 in this example. Clevis joint 46includes an elongate member, in this fastener, in this case bolt 50. Thebolt extends through pole 44 and spans across and couples to clevis vianut 52. Clevis joints per se are known to those skilled in the art andclevis joint 46 will thus not be described in further detail.

As seen in FIG. 7 , corner bead roller apparatus 30 includes a first oneor more roller assemblies, in this example first and second rollerassemblies 54 and 56. The first and second roller assemblies align witheach other and planar portion 40 of bracket 32 in this example. Cornerbead roller apparatus 30 includes a second one or more rollerassemblies, in this example third and fourth roller assemblies 58 and60. The third and fourth roller assemblies align with each other andplanar portion 42 of bracket 32 in this example. The third and fourthroller assemblies 58 and 60 are angled relative to first and secondroller assemblies 54 and 56. Alternatively there may only be two rollerassemblies which are angularly spaced from each other, such first andthird roller assemblies 54 and 58 or second and four roller assemblies56 and 60.

At least one and in this example first and third roller assemblies 54and 58 couple to and extend outwards from bracket 32 adjacent distal end36 of bracket 30; however, the latter is not is strictly required. Atleast one and in this example second and fourth roller assemblies 56 and60 couple to and extend outwards from proximal end 34 of the bracket;however, here too the latter is not strictly required.

As seen in FIG. 5 , each roller assembly 54 includes a rollerpositioning assembly 62. Each roller positioning assembly includes inthis example a shaft 64 coupled to and extending outwards from bracket.Each shaft has a proximal end 66, a distal end 68 spaced-apart from theproximal end thereof, and a longitudinal axis 70 extending between theends thereof. Shaft 64 includes a first end portion, in this example athreaded end portion 72 extending from the proximal end thereof towardsthe distal end thereof. As seen in FIG. 2 , each shaft couples tobracket 32 via threaded end portion 72 thereof in this example.

Referring back to FIG. 5 , each shaft 64 includes a second end portion,in this example an enlarged end portion 74 spaced-apart from thethreaded end portion thereof. The enlarged end portion may also bereferred to as an enlarged second end portion. Enlarged end portion 74of shaft 64 extends from distal end 68 towards proximal end 66 of theshaft.

As seen in FIG. 7 , each shaft includes a socket, in this example arecessed socket 76. The recessed socket extends from distal end 68 ofthe shaft towards proximal end 66 of the shaft seen in FIG. 5 in thisexample. Referring back to FIG. 7 , recessed socket 76 is shaped to matewith a tool bit (not shown) so that a tool (not shown) to which the toolbit couples, may selectively rotate the shaft via the recessed socket.Rotation of shaft 64 in a first or clockwise direction 78 causes theshaft and thus roller assembly 54 to incrementally move towards planarportion 40 of bracket 32. Rotation of the shaft in a second orcounter-clockwise direction 80 causes the shaft and thus roller assembly54 to incrementally move outwards from the planar portion of thebracket. Recessed socket 76 of shaft 64 is thus configured to enablepositioning of the shaft to be selectively adjusted relative planarportion 40 of bracket 32 to which the shaft couples. The recessed socketof the shaft is also configured to enable the shaft to be selectivelyremoved from the bracket.

Referring to FIG. 5 , each roller positioning assembly 62 includes inthis example a first planar member or washer 84 shaped to abut enlargedend portion 74 of shaft 64. Each roller positioning assembly includes inthis example at least one and in this case a plurality of additionalplanar members or washers 86, 88 and 90. As seen in FIG. 2 , theadditional washers are configured to be positioned adjacent threaded endportion 72 of shaft 64. Washers 86, 88 and 90 are slidable relative toshaft 64 and axially moveable in part relative to each other in thisexample. The washers as well as enlarged end portion 74 of the shaftseen in FIG. 5 may be referred to as a pair of spaced-apart protrusionswhich extend radially outwards from the shaft thereof.

Referring now to FIG. 2 , each roller assembly 54 includes a roller 92.The roller has a proximal end 94 near or adjacent bracket 32 and againstwhich washer 86 abuts in this example. Roller 92 has a distal end 96spaced-apart from the proximal end thereof. As seen in FIG. 7 , recessedsocket 76 of shaft 64 is axially inwardly spaced from distal end 96 ofits corresponding roller in this example. Each roller is continuouslytapered from distal end 96 thereof to proximal end 94 thereof. As seenin FIG. 1 , each roller 92 is an isosceles trapezoid in side profile inthis example.

Referring to FIG. 3 , each roller 92 includes an inner portion 98configured to rotatably coupled to and be axially moveable in partrelative to its shaft 64 seen in FIG. 5 . Alternatively the innerportion of roller assembly 54 may be referred to as or considered theroller. Inner portion 98 of roller 92 has a first or proximal end 100, asecond or distal end 102 spaced-apart from the proximal end thereof anda longitudinal axis 104 extending between the ends thereof. Thelongitudinal axis of the inner portion of the roller may also bereferred to and coincides with the longitudinal axis of the roller as awhole.

Inner portion 98 of roller 92 has an outer surface 106 extending betweenends thereof. The outer surface of the inner portion of the roller iscontinuous in this example. Outer surface 106 of inner portion 98 ofroller 92 extends radially outwards relative to longitudinal axis in adirection 95 extending from end 94 to end 96 at a constant angle θrelative to the shaft and longitudinal axis 104 in this example. Theouter surface of inner portion 98 of roller 92 is frustoconical in shapein this example.

Still referring to FIG. 3 , inner portion 98 of roller 92 has a centralbore 108 extending between ends 94 and 96 thereof. As seen in FIG. 4 ,the central bore is shaped to slidably receive shaft 64, seen in FIG. 5, therethrough. Referring back to FIG. 4 , inner portion 98 of roller 92has an outer or distal bore 110 in communication with central bore 108.The distal bore extends from distal end 96 towards proximal end 94 ofthe inner portion of the roller. Distal bore 110 is shaped to receiveenlarged end portion 74 of shaft 64 as well as washer 84 therewithinseen in FIG. 5 ; however, at least the latter is not strictly required.

Roller 92 includes a spacer or proximal end portion 112 that is annularin this example. The proximal end portion extends from proximal end 94towards distal end 96 of the roller. Proximal end portion 112 and innerportion 98 of roller 92 are integrally connected together so as to forma unitary whole in this example. The proximal end portion of the rolleris radially inwardly spaced from outer surface 106 of the inner portionof the roller in this example. Proximal end portion 112 extends aboutdistal bore 110 in this example. The proximal end portion is shaped tobe adjacent to and slidably receive washer 86 seen in FIG. 5 in thisexample.

As seen in FIG. 4 , each roller 92 includes an outer portion, in thisexample a sleeve 114. The sleeve couples to and extends about innerportion 98 thereof. Sleeve 114 is tubular in shape in this example. Thesleeve has a first or proximal end 116 and a second or distal end 118spaced-apart from the proximal end thereof. Referring to FIG. 2 , thedistal ends 96 and 118 of inner portion 98 and sleeve 114 of each rolleralign flush with each other in this example. As seen in FIG. 7 , distalend 68 of shaft 64 aligns flush or inwardly spaced relative to thedistal ends of the sleeve and the inner portion of the roller thereof.

As seen in FIG. 4 , sleeve 114 of roller 92 has an inner surface 115that is continuous in this example. Referring to FIG. 2 , the innersurface of sleeve 114 extends outwards at a constant angle Q relative toshaft 94 and longitudinal axis 104. The diameter D₁ of inner surface 115of the sleeve at a given longitudinal position of roller 92 may beslightly smaller than the corresponding diameter Do of outer surface 106of inner portion 106 of the roller. Sleeve 114 of the roller is thusshaped to be stretched about and frictionally couple to the innerportion of the roller. The sleeve of the roller has an outer surface 120spaced-apart from and opposite inner surface 115 thereof. The outersurface of the sleeve is smooth and continuous in this example. Innersurface 115 and outer surface 120 of sleeve 114 of roller 92 arefrustoconical in shape in this example.

Outer surface 120 of sleeve 114 extends outwards at a constant anglerelative to longitudinal axis 104 of shaft 64 thereof, in this exampleangle β. Angle β is acute and is a value in the range of 1 to 5 degreesin this example; however, this is not strictly required and other anglesmay be possible in other embodiments. Sleeve 114 of roller 92 flaresoutwards at a constant angle relative to longitudinal axis 104 ofcorresponding shaft 64. Sleeve 114 may be referred to as an outer wallof roller 92 extending from proximal end 94 to distal end 96 of theroller. The outer wall may be referred to as including an outerperipheral surface and/or comprising outer portion of the sleeve.

Referring to FIG. 3 , sleeve 114 of roller 92 is more compressiblerelative to inner portion 98 of the roller. The sleeve is made of asofter material relative to that of the inner portion of the roller.Sleeve 114 is made of a selectively deformable material, in this examplean elastomer, in this case silicone rubber; however, this is notstrictly required and other materials may be used in other embodiments.Sleeve 114 is made of a clear or at least semi-transparent material inthis example; here too this is not strictly required and non-transparentmaterials may be in other embodiments.

Inner portion 98 of roller 92 is more rigid relative to that of thesleeve of the roller. The inner portion of the roller is made of a hardmaterial relative to that of the sleeve, such as metal or hard plastic;however, this is not strictly required and other types of materials maybe used in other examples.

Referring to FIG. 7 , each roller 92 rotatably couples to itscorresponding shaft 64 and rotates about longitudinal axis 104 of itscorresponding shaft. Thus, first and second roller assemblies 54 and 56(and rollers 92 thereof) rotate about axes 104 and 105 which areperpendicular to axes 107 and 109 of third and fourth roller assemblies58 and 60 (and rollers thereof). This is shown in FIG. 2 by axes 104 and107 that extend perpendicular to each other. Referring to FIG. 1 , oneor more rollers of first and second roller assemblies 54 and 56 may bereferred to a first arrangement of one or more rollers. One or morerollers of third and fourth roller assemblies 58 and 60 may be referredto as a second arrangement of one or more rollers angularly spaced fromthe first arrangement of one or more rollers.

As seen in FIG. 8 , for each roller assembly 58, roller 92 thereof ispositioned between and loosely held in place via protrusions thereof, inthis example washers 90 and enlarged end portion 74 of shaft 64 thereof.The washers may function to inhibit the roller from abutting planarportion 40 of bracket 32 and/or becoming dislodged from the shaft. Eachroller 92 is configured to be moveable and in this example slidable inpart relative to its corresponding shaft 64 thereof. The roller is thusaxially moveable at least in part relative to shaft 64, about which theroller is rotatably mounted. Roller 92 has an extended position shown inFIG. 8 by roller assembly 54 in which enlarged end portion 74 of shaft64 is axially inwardly spaced from proximal end portion 112 and distalend 96 of roller. The roller is moveable from the extended position to aretracted position by an axially-extending distance D and as shown byroller assembly 56, in which in this example enlarged end portion 74′ ofshaft 64′ aligns flush with proximal end portion 112′ and distal end 96′of roller 92′ in this example.

Each roller 92 may thus selectively abut washers 90 and/or enlarged endportion 74 of its corresponding shaft 64. Each roller thus operativelycouples to, is rotatable relative to, extends outwards from and islinearly moveable relative to bracket 32 in this example. Each shaft 64and pair of corresponding protrusions or washers 90 and enlarged endportion 74 thereof may be referred to as a roller mount that enablescorresponding roller 92 to rotate about and be linearly moveable in partrelative to longitudinal axis 104 thereof.

Referring to FIG. 6 , rollers 92 of first and second roller assemblies54 and 56 thus rotatably couple to first planar portion 40 of bracket 32via shafts 64 in this example. Proximal ends 94 of the rollers of thefirst and second roller assemblies extend laterally outwards from thefirst planar portion of the bracket in this example; however, this isnot strictly required. The rollers of third and fourth roller assemblies58 and 60 rotatably couple to second planar portion 42 of bracket 32 viashafts 64′ in this example. Proximal ends 94′ of rollers 92′ of thethird and fourth roller assemblies extend laterally outwards from thesecond planar portion of the bracket in this example; however, here toothis is not strictly required.

Proximal ends 94 of rollers 92 of first and third roller assemblies 54and 58 extend longitudinally outwards from distal end 36 of bracket inthis example; however, this is not strictly required. Proximal ends 94″of rollers 92″ of second and fourth roller assemblies 56 and 60 extendlongitudinally outwards from proximal end 34 of bracket in this example;however, here too this is not strictly required.

Each roller 92 is tapered and in this example an isosceles trapezoid infirst and second side profiles when not in use as seen in FIGS. 2 and 8, for example.

In operation and referring to FIG. 9 , a corner bead 122 is coupledadjacent peripheral portions 124 and 126 of planar pieces of drywall 128and 130 so as to form a corner 132. A joining compound, in this exampledrywall joint compound 134 is applied so as to extend along peripheralportions 136 and 138 of corner bead 122 and promote coupling of thecorner bead to the peripheral portions 124 and 126 of the drywall 128and 130.

Rollers 92 of corner bead roller apparatus 30 are next positioned inplace via pole 44 gripped by person 140. The rollers are rolled alongand against the side and peripheral portions 136 and 138 of corner bead122, as shown by arrow of numeral 142, so as to smooth out the drywalljoint compound 134 and promote a flush connection between the cornerbead and adjacent drywall 128 and 130 to which the corner bead abuts.Rollers 92 thus in use extend against corner portions 144 and 146 ofdrywall 128 and 130. The rollers are configured to resiliently deform atleast in part when in use, in this example sleeves 114. In this exampleat least outer halves 148 of rollers 92, which are shaped to align withperipheral portions 136 and 138 of corner bead 122, are configured toresiliently deform when in use. Sleeves 114 seen in FIG. 1 may deform inpart in use when biased against the corner bead such that each roller 92may be substantially a right-angled trapezoid (shown by numeral 91) in afirst side profile seen in FIG. 10 and may be an isosceles trapezoid(shown by numeral 93) in a second said side profile seen in FIG. 9 whichis perpendicular to the first side profile; however this is not strictlyrequired.

Referring to FIG. 11 , corner bead roller apparatus 30 during the abovedescribed process may be periodically wetted and/or cleaned bysubmerging (seen by arrow 149) rollers 92 into liquid 150 held bycontainer 152, which may comprise water and/or a cleaning solutions.

Finally and referring to FIG. 12 , a finishing tool 154 comprising oneor more sponges 156 and 158 shaped to extend along peripheral portions136 and 138 of corner bead 122, may be moved therealong (as shown byarrow of numeral 160) for finishing the outside corner 132 as formed bythe corner bead. This may function to further smoothen out the drywalljoint compound 134 so as to promote formation of a continuous exteriorsurface between drywall 128 and 130 and corner bead 122. A suitablefinishing tool in this regard is described in U.S. Pat. No. 9,447,591 toMcKay, the disclosure of which is incorporated herein by reference.However, such a finishing tool is not strictly required and othermethods or tools for finishing the corner may be used in other examplesas may be appreciated by someone skilled in the art.

FIG. 13 shows a corner bead roller apparatus 30.1 according to anotheraspect. Like parts have like numbers and functions as corner bead rollerapparatus 30 shown in FIGS. 1 to 12 with the addition of decimalextension “0.1”. Corner bead roller apparatus 30.1 is substantially thesame as corner bead roller apparatus 30 shown in FIGS. 1 to 12 with thefollowing exception.

Proximal end portions 112.1 of rollers 92.1 are shaped to abut distalends 118.1 of sleeves 114.1 in this example. The proximal end portionsof the rollers are shaped to further inhibit movement of the sleevesrelative to the inner portions 98.1 of the rollers in this example.

FIG. 14 shows a corner bead roller apparatus 30.2 according to a furtheraspect. Like parts have like numbers and functions as corner bead rollerapparatus 30 shown in FIGS. 1 to 12 with the addition of decimalextension “0.2”. Corner bead roller apparatus 30.2 is substantially thesame as corner bead roller apparatus 30 shown in FIGS. 1 to 12 with thefollowing exception.

In this embodiment, for each roller assembly 54.2 one of the protrusionsthereof comprises a flange 112.2 instead of a washer. The flanges may bereferred to as the proximal end portions of the rollers. Each flange112.2 couples to and extends radially outwards from corresponding shaft64.2. The flange is circular in profile in this example; however, thisis not strictly required. Flange 112.2 selectively abuts proximal end94.2 of roller 92.2 thereof. Flange 112.2 extends radially outwards fromthe proximal end of the roller in this example. The flange functions toinhibit roller 92.2 from abutting bracket 32.2 and/or becoming dislodgedfrom shaft 64.2. Distal end 96.2 of the roller extends radially outwardsto a greater extent compared to flange 112.2 thereof in this example;however, this is not strictly required.

It will be appreciated that many variations are possible within thescope of the invention described herein. Where a component (e.g. anapparatus, assembly, device, etc.) is referred to herein, unlessotherwise indicated, reference to that component (including a referenceto a “means”) should be interpreted as including as equivalents of thatcomponent any component which performs the function of the describedcomponent (i.e., that is functionally equivalent), including componentswhich are not structurally equivalent to the disclosed structure whichperforms the function in the illustrated exemplary embodiments of theinvention.
